DUMP-WAGON.

Specification of Letters Patent.

Patented A11 22, 1911.

To all whom it may concern:

Be it known that we, ROBERT M. Wrrrrn and EARL T. ADAMS, citizens of theUnited States, residing at Portsmouth, in the county of Scioto, State ofOhio, have invented a new and useful Dump-d agon, of which the followingis a specification.

This invention relates to dumping wagons of that type designed todischarge the load from the rear of the body.

The principal object of the invention is to provide a wagon of thischaracter the rear axle of which is so shaped and located as toconstitute the support whereby the body is maintained normally inelevated position.

Another object is to provide a supporting axle designed to be shiftedfrom a predetermined position so as to permit the wagon body to dump itscontents, mechanism being utilized whereby the axle can be automaticallyreturned to its initial position, this return movement resulting in thereturn of the wagon body to raised position.

A further object is to provide novel means for locking the wagon body inelevated position, said locking means, as well as the axle-operatingmeans being under the control of a single lever.

Another object is to provide a wagon of this type which can be dumpedwhile the team is going forward, standing still, or backing, thus makingit easy to dump the contents of the wagon over an embankment.

A further object is to provide a dumping wagon which is devoid ofcomplicated parts and will not readily get out of order.

With these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :-Figure 1 is a side elevation of a wagon embodying thepresent improvements, the position of the wagon body when dumped beingindicated by dotted lines. Fig. 2 is a central longitudinal sectionthrough the rear portion of the wagon. Fig. 3 is a plan view of theparts shown in Fig. 2. Fig. 4 is an elevation of the hub of the wheelshown in Fig. 3 and showing adjacent parts partly in section and partlyin elevation.

Referring to the figures by characters of reference 1 designates themain frame of the wagon, the same being mounted in the ordinary mannerat its front end while the rear end of the frame is provided withdownwardly and rearwardly inclined side portions 2 in which arejournaled the end portions of the rear axle 4:. The rear supportingwheels 5 are mounted for rotation upon the end portions of the axle, andsecured to the inner end of the hub of each of these wheels is one ofthe elements 6 of a friction clutch. Supporting strips 7 extend upwurdlvand rearwardly from the end portions of the arms 2 and are attached tothe sides of a tailboard S which is thus held fixed at all times withrelation to the frame 1, the sides 9 of said tailboard being eachprovided with a curved edge 10 designed to be engaged by thecorrespondingly curved end of one of the sides 11 of the tiltable wagonbody 12. A rod 13 connects the sides of the frame 1 at the upper ends ofthe arms 2 and brackets 14 are pivotally mounted 011 this red and aresecured to and extend downwardly from the bottom of the wagon body 12.The axle 41 is arched, as indicated at 15, this arch being provided withanti-friction rollers 16, designed, when the arch is extended upwardly,to contact with the bottom of the wagon-body 12 and support said body ina substantially horizontal position. A locking catch 17 is pivotallyconnected to each side of the main frame 1 and has a notch 18 designedto receive the arched portion 1.5 of the axle so as to hold it inupstanding position. Each catch 17 is connected to the adjoining strip 7by means of a toggle 19 having a flexible link 20 connected to themiddle portion thereof. This link loosely engages a rod 21 which isadapted to slide and to swing within a guide 21 which is secured to theadjoining arm 2, and collars 22 are arranged upon the rod so as to causethe link 20 to be shifted with the rod 21. An actuating lever 28 ismounted to swing laterally in a bracket 23 and said bracket is pivotallyconnected to the side of the frame 1 adjacent the front end thereof,whereby the lever can be swung both backward and forward and laterally,the said rod 21 being loosely attached to the lever at a point removedfrom the fulcrum thereof.

Each end portion 3 of the rear axle 4 has a cup-like clutch member 24keyed or otherwise secured to it and designed to receive the adjoiningclutch member 6 heretoforereferred to. It is to be understood of coursethat this member 24 is capable of sliding upon the axle-end 8. Anannular groove 25 is formed within the member 24 and is looselyengagedby a fork 26 formed at the rear end of the rod 21.

It is of course to be understood that when the arched portion 15 of theaxle is engaged by the catches 17 said arched portion will act as asupport for the rear end of the wagon body and said body will thus beheld firmly against the side 9 of the tail-board 8. When it is desiredto dump the contents of the body the lever 23 is swung forward so as topull the rod 21 longitudinally. Motion will, therefore be transmittedthrough the link 20 to each of the toggles 19 and said toggles will beextended and will lift the catches 17 out of engagement with the axlearch 15. The axle will therefore swing downwardly so as to permit therear portion of the wagon body to drop to the ground, as indicated bydotted lines in Fig. 1, the lower portion of said body assuming aposition within the arched portion of the axle. This operation canobviously be performed while the wagon is traveling in either direction, or while it is stationary.

After the wagon has been dumped the same can be moved forward and, atthe same time, the driver shifts the lever 23 laterally so as to rockthe rod 21 laterally and cause the forked end of the rod 21 to swingoutwardly and shift the clutch member 24 into frictional engagement withthe clutch member 6. Said member 24 will therefore be rotated with thewheel 5, and the axle 4 will be caused to also rotate. As a result thearch 15 will swing upwardly and thus return the wagon body 12 to itsraised position. As the arch portion 15 passes under the notches 18 inthe catches 17, said catches will automatically engage said archedportion and thus lock it in raised position.

It is to be understood that the wagon may be provided with two levers 23and two sets of mechanism such as herein described, or, if preferred,only one'lever and one set of locking and clutch mechanism may beutilized.

While the improvements herein described have been set forth asespecially designed for use in connection with dumping wagons, it is tobe understood that dumping cars may be similarly constructed.

Various changes can of course be made in the construction andarrangement of the parts without departing from the spirit orsacrificing any of the advantages of the invention.

What is claimed is 1. A vehicle including a tiltably supported body, arevoluble arched axle for holding the body against tilting movement,means for locking the axle against move ment with relation to the body,means for releasing the axle to tilt the body, and means operated by themovement of the vehicle in one direction, for actuating the axle toreturn the body to raised position.
